Status Commands

Status commands program the dc source status registers. The dc source has three groups of status registers; Operation, Questionable, and Standard Event. The Standard Event group is programmed with Common commands as described later in this section. The Operation and Questionable status groups each consist of the Condition, Enable, and Event registers and the NTR and PTR filters. Chapter 5 explains how to read specific register bits and use the information they return.

STATus:OPERation[:EVENt]?

This query returns the value of the Operation Event register. The Event register is a read-only register, which stores (latches) all events that are passed by the Operation NTR and/or PTR filter. Reading the Operation Event register clears it.

Query Syntax			STATus:OPERtion[:EVENt]? (@<channel list>)
Parameters			None
Returned Parameters			<NR1>(register value)
	Examples		STAT:OPER? (@1)
Related Commands			*CLS STAT:OPER:NTR				STAT:OPER:PTR

STATus:OPERation:CONDition?

This query returns the value of the Operation Condition register. That is a read-only register, which holds the live (unlatched) operational status of the dc source.

Query Syntax	STATus:OPERation:CONDition? (@<channel list>)
Parameters	None
Examples	STAT:OPER:COND? (@1)
	STATUS:OPERATION:CONDITION? (@1)
Returned Parameters	<NR1> (register value)

STATus:OPERation:ENABle

This command and its query set and read the value of the Operational Enable register. This register is a mask for enabling specific bits from the Operation Event register to set the operation summary bit (OPER) of the Status Byte register. This bit (bit 7) is the logical OR of all the Operatonal Event register bits that are enabled by the Status Operation Enable register.

Command Syntax	STATus:OPERation:ENABle<NRf>,(@<channel list>)
Parameters	0 to 32767
Preset Value	0
Examples	STAT:OPER:ENAB 1312,(@1)
Query Syntax	STATus:OPERation:ENABle? (@<channel list>)
Returned Parameters	<NR1> (register value)
